Salted paper print at the Fine Arts Library

Salted Paper Prints: Process and Purpose
A Collaborative Workshop in Photograph Conservation

In collaboration with the Foundation for the American Institute for Conservation of Historic and Artistic WorksHarvard Art Museums, and Houghton Library, Harvard Weissman Preservation Center (WPC) is hosting a symposium on salted paper prints on September 14th and 15th. Registered participants will be able to attend a special viewing of salted paper prints from the Harvard Fine Arts Library‘s historic photographs collection on September 13th.

A salted paper print, or simply salt print, is a photographic printing process whereby paper is coated with salt solution and then a silver nitrate solution to capture images. It was a popular photographic printing technique between 1839 and approximately 1860.[1]

WPC has undertaken a university-wide project, the Salt Print Initiative, to preserve and enhance access to salt prints across campus, including inventorying the salt prints held by individual repositories, including the Fine Arts Library.

This symposium will present a multi-disciplinary, two-day program that focuses on the preservation, characterization, use, and interpretation of the salt print process, now over 175 years old. Read more about the symposium and how to register.


Staff from Harvard Weissman Preservation Center selected some salted paper prints from our collection for the initial presentation at the Fine Arts Library in December, 2016.

Stay tuned for more images from the historic photographs collection.
